This paper describes a graphical teaching tool, D 2 EAC, which is used to demonstrate the equal area criterion to the undergraduate students. Distinguishing from the textbooks and the common teaching tools, we demonstrate this basic but powerful criterion dynamically. Moreover, we generalize this criterion so that the damping effect and the Superconductive Magnetic Energy System (SMES) control devices can be included. Some solved examples, which include the transient stability analysis and the transient stability enhancement using a SMES, are presented.
